Answer:
Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth. This means gravity makes the Moon accelerate all the time, even though its speed remains constant.
Explanation:
A equilateral triangle?
They don't have right angles, and all sides are the same.
<span>The two factors that determine the shape of a protein </span><span><span>
1. </span> Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement. </span>
<span><span>2. </span>Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure</span><span>

Answer:
Concentration gradient means difference in solute concentration among two regions of a solution.
Explanation:
When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .
Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.
During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.
